I would like to thank you all for taking the trouble to reply to the question .

I've just had a quick check on the replies so far and I make 18 have intact marriages, 10 have failed , I've not counted multiple divorces which if I did would almost even the figures up .

I hope more will take take the trouble to add to the figures , I'm not concerned about which label you use whether it be CDer, TG or TS .
